Understanding the UV Index is crucial for residents of Baijiazhuang, China, where the combination of a Dwb climate and intense sunlight can lead to increased risks of skin damage. With peak UV levels soaring to 11 at midday, being aware of these fluctuating levels is essential for preventing sunburn and protecting skin health. Regularly monitoring the UV Index allows locals to take necessary precautions during the hottest hours, particularly from 10 AM to 2 PM, thereby ensuring safer outdoor activities and reducing the risk of long-term skin issues. Stay informed and protect yourself against the sun's harmful rays!

As the sun rises, the intensity peaks sharply in the late morning, reaching a striking 11 at 12:00 PM, making it the most potent hour of the day. Following this zenith, the index gently declines, tapering off to 10 at 1:00 PM, then dropping to 9 by 2:00 PM. The afternoon continues this downward trend with values of 7 at 3:00 PM, 4 at 4:00 PM, and finally settling to a comfortable 2 by 5:00 PM. As twilight approaches, the UV Index decreases to a safe 1 by 6:00 PM, lingering at this low level until 7:00 PM.
